Sofar everyone here has been really helpful, and has helped me complete 2 projects which I greatly appreciate. My question is this one:

Snort, the opensource IDS, can only output it's results to a file from my experience. Assuming what I just said is 100% true, this is my question: How would I go about constructin a perl script that reads from that file and only returns the changes from it? IE: the script would read it once, and then the next time it reads it the script returns only the differences (changes) to the logfile.

Sofar, what I have seen is seek() and I tell it to read from the EOF and backwards... But if that is the method, how does one get it to detect "Oh, I know that part... I read it from the last time i did analysis of this file."?

Any help is greatly appreciated.
